摘要： A valve timing control system for an internal combustion engine allows an actual valve timing (Ta) for an intake valve (17) and/or an exhaust valve (18) to converge speedily to a desired valve timing (To) even when control quantities for the engine are initialized immediately after power-on or restoration of a normal operation state from an abnormal state, to thereby suppress degradation of engine performance and exhaust gas quality. The valve timing control system includes an actual valve timing control means (204) for generating a control quantity (i) for the variable valve timing mechanism (40) so that a timing deviation (ER) of the actual valve timing (Ta) from the desired valve timing (To) becomes zero, an integral control means (205) for arithmetically determining an integral correcting value (&Sgr;Ki) by integrating the timing deviation (ER) for thereby correcting the control quantity (i), a means (207) for detecting as an initializing condition an engine operation state in which the integral correcting value (&Sgr;Ki) is to be initialized, and a means (208) for initializing the integral correcting value (&Sgr;Ki) to an optimum value conforming with the engine operation state when the initializing condition is detected, wherein the initializing means (208) is so designed as to set an initial value of the integral correcting value (&Sgr;Ki) to a negative value.

摘要： A valve timing control system for an internal combustion engine, comprising a required advance amount calculating section for calculating a required advance amount on the basis of operating condition of the engine, a valve timing control section for calculating a valve timing control variable on the basis of an obtained advance amount and the required advance amount calculated by the required advance amount calculating section, and a time period measuring section for measuring an elapsed time after the start of the engine. The required advance amount calculating section makes a calculation so that the required advance amount assumes a value smaller than that in an normal state until the time period measuring section measures a predetermined period of time. Hence, exhaust gas clarification immediately after the engine start, fuel consumption and drivability can be improved.

摘要： A system for operating an internal combustion engine includes an intake valve moveable between a first position at which fluid is blocked from flowing to or from the cylinder and a second position at which fluid is allowed to pass to or from the cylinder. The system includes a fluid actuator selectively operable to hold the intake valve from moving to the first position during a portion of a compression stroke and a control valve configured to control fluid flow between a source of fluid and the fluid actuator. A fuel supply system supplies a predetermined amount of fuel to the cylinder at an appropriate time during an engine cycle based on at least one engine operating parameter, and a controller determines a need to de-rate the engine based on a sensed parameter relating to source fluid viscosity during a cycle in which the fluid actuator is not operated.

摘要： Processing conditions are determined on the basis of an operation range. After IG-OFF, an intake valve opening timing is advanced to 20° CA BTDC, and an exhaust valve closing timing is retarded to 20° CA ATDC. By controlling the intake and exhaust valve timings as described above, it is possible to reduce the fuel sticking to the intake passage. Particularly in the case of cold engine starting before activation of the catalyst, it is possible to prevent direct exhaust of HC emissions and accordingly to reduce emissions because of the decreased amount of fuel sticking to the intake passage.
摘要翻译：处理条件基于操作范围确定。在IG-OFF之后，进气门打开正时提前到20°CA BTDC，排气门关闭正时延迟到20°CA ATDC。通过如上所述控制进气门和排气门正时，可以减少燃料粘在进气道上。特别是在催化剂活化前冷起动器的情况下，可以防止HC排放物的直接排放，并且因此能够减少排放量，因为燃料的量滞留在进气通道上。
